In operation, the hot air pipe 14 blows hot air to the side edge of the paper box and part of the hot air is blown into the ventilation cavity 21, if the hot air which is not directly applied to the side edge of the paper box is utilized, waste is caused, therefore, the first hole 24 is formed in one end of the drying plate 2 close to the paper box, the hot air can directly act on the side surface of the paper box through the first hole 24, the side surface of the paper box can be acted by the hot air, the paper box can be dried more fully, the first hole 24 is obliquely arranged, the acting area is larger, the hot air can be better received, the hot air flows out of the first hole 24, the position, which is located at one end of the front end surface of the ventilation cavity 21 and is closer to the side surface of the drying plate 2, of the paper box is further caused by the arrangement, and the hot air entering the ventilation cavity 21 flows out of the surface of the paper box from the first hole 24, so that the utilization of the hot air can be more fully.
As a specific embodiment of the present invention, a vertical first slot 25 is uniformly arranged on one surface of the drying plate 2 close to the paper box, the first hole 24 is located inside the first slot 25, and the top of the first slot 25 is communicated with an area above the drying plate 2.
During operation, just be equipped with a groove 25 to a hole 24 in the one side that is close to the carton of stoving board 2, can make the steam that flows from a hole 24 be after acting on the surface of carton, discharge steam along a groove 25, play a guide's effect to steam, be favorable to going on smoothly of stoving work, the lower terminal surface of a groove 25 is closed, can make steam receive ascending air guide effect like this only, be favorable to carrying steam's steam by air discharge fan 5 discharge stoving case 1.
As a specific embodiment of the present invention, the air baffle 212 is vertically disposed in the middle of the ventilation cavity 21, and cambered surfaces 213 are disposed on two sides of the air baffle 212.
During operation, because the position that every side corresponds all is equipped with hot-blast main 14, the both sides of ventilation chamber 21 all can get into steam like this, if do not take any measure, will lead to the steam that ventilation chamber 21 both sides got into to produce the phenomenon emergence of hedging in ventilation chamber 21 inside, influence the stability of hot air flow greatly, make the efficiency of work drop, the vertical gas baffle 212 that sets up in ventilation chamber 21 intermediate position, just avoided ventilation chamber 21 both sides entering steam to produce the phenomenon of hedging in ventilation chamber 21 inside, be equipped with cambered surface 213 in the both sides of gas baffle 212, just can make the transmission of hot air more smooth and easy.
As a specific embodiment of the present invention, a bent piece 26 is disposed on a side of the drying plate 2, one end of the bent piece 26 close to the drying plate 2 is connected to a front end surface of the ventilation cavity 21 of the drying plate 2, and one end of the bent piece 26 far away from the drying plate 2 is opposite to the air outlet 141 of the hot air pipe 14 and is perpendicular to the end surface where the air outlet 141 is located; and a gap is arranged between the bent pieces 26 of the adjacent drying plates 2.
During operation, in the process that the hot air blows to the side of the paper box, the bent pieces 26 are arranged on the side of the drying plate 2, gaps are formed between the bent pieces 26, so that when the hot air blows to the side of the paper box, hot air can be respectively drained into the ventilation cavity 21 where the drying plate 2 is located by the bent pieces 26 of the adjacent drying plate 2, and the hot air passing through the gaps between the bent pieces 26 can blow to the side of the paper box, so that the hot air sprayed out by the hot air pipe 14 is effectively split, all parts of the paper box can be heated well, and the drying efficiency is improved.
